Advanced Systems Technology, Inc., commonly known as AST, is a U.S.-based small business that provides technical and mission-support services to government and defense customers.
The company was founded in 1984 in Lawton, Oklahoma, by former military professionals. Its early work focused on engineering and technical support for Army combat systems. Over time, AST expanded into simulation, training, software, logistics, systems integration, maintenance, range operations, and sustainment.
Today, AST describes itself as a mission-focused organization supporting customers throughout the lifecycle of training, simulation, maintenance, logistics, and related technical systems.
Its experience is particularly connected to U.S. Army training and simulation programs, although its capabilities cover a broader range of government requirements.
What Does Advanced Systems Technology Do?
AST works across several areas that are important to military readiness and government operations. Its capabilities include:
- Training aids, devices, simulators, and simulations
- Live, Virtual, and Constructive training environments
- Range operations
- Systems integration
- Software and computer-based training
- Logistics management
- Maintenance and sustainment
- Infrastructure modernization
- Fielded-system support
- Program management
This broad approach allows the company to support projects beyond the initial development stage. Its services can extend from system deployment and testing through ongoing maintenance and operational support.
Training and Simulation Capabilities
One of AST’s most important areas is military training and simulation.
The company has more than 40 years of experience supporting simulation and instrumentation in Live, Virtual, and Constructive (LVC) training environments. These environments allow military organizations to conduct realistic training using a combination of physical exercises, virtual systems, and computer-generated scenarios.
AST also supports Training Aids, Devices, Simulators and Simulations (TADSS). These systems can help personnel practice procedures and prepare for operational situations without relying exclusively on real-world equipment or exercises.
Support can include development, integration, maintenance, sustainment, and technical assistance. That lifecycle approach is important because training systems need to remain functional and relevant as requirements, platforms, and operational concepts change.
Systems Integration and Software Support
Modern defense programs often depend on multiple technologies working together. Systems integration helps connect hardware, software, communications, training platforms, and other components into an operational environment.
AST has experience supporting Command, Control, Communications, Computers, and Intelligence (C4I) systems, as well as training networks, computer-based training, simulations, and model-based studies and analysis.
Software and systems support can be especially important when organizations operate complex technical environments. Instead of treating each component as an isolated system, integration focuses on how the different technologies interact and support a larger mission.
This type of work requires technical expertise as well as an understanding of the operational environment in which the systems will be used.
Logistics, Maintenance, and Lifecycle Support
Technology does not provide long-term value if it cannot be maintained after deployment.
For this reason, lifecycle support is another major part of AST’s capabilities. The company provides maintenance, logistics, deployment support, sustainment, and fielded-system services. Its capabilities include maintenance support for wheeled vehicles, aircraft, and TADSS.
Lifecycle support can help government organizations keep critical systems operational over extended periods. It also creates continuity between development, deployment, maintenance, and eventual modernization.
For large defense programs, this approach can be particularly useful because operational requirements can continue for years after a system has initially been introduced.
Range Operations and Infrastructure
Military training also depends on reliable physical infrastructure.
AST supports range operations and related infrastructure requirements, including communications towers, cabling, and fiber backbone upgrades. These services help create and maintain the technical environment required for training activities and range operations.
Infrastructure modernization is increasingly important as training environments become more connected and technology-dependent. Reliable communications and networking can support the movement of information between systems, personnel, and training components.
AST’s Government and Defense Experience
AST’s history is closely connected to U.S. government and Department of Defense requirements.
The company says it has provided more than 40 years of continuous mission-critical support and has worked through multiple organizational transitions involving Army simulation, training, and testing missions.
AST also operates as both a prime contractor and a subcontractor or teaming partner. Its current capabilities include support for different contract structures and government contract vehicles.
One notable recent development is AST’s 2026 award of an OASIS+ prime contract as a Service-Disabled Veteran-Owned Small Business (SDVOSB) in the Technical & Engineering and Logistics domains. The company says this expands its ability to support federal agencies through the governmentwide contract vehicle.
Why Mission-Focused Technical Support Matters
Government and defense technology projects often involve more than simply developing a new product.
A successful program may require:
- Initial engineering and design
- System integration
- Testing and evaluation
- Training
- Deployment
- Maintenance
- Logistics
- Modernization
- Long-term sustainment
Organizations that can support multiple stages of this lifecycle can provide continuity throughout a program.
This is one reason companies such as AST emphasize lifecycle support rather than concentrating exclusively on individual technologies.
Advanced Systems Technology in 2026
In 2026, AST continues to position itself around government and defense mission support. Its current service portfolio covers training and simulation, range operations, logistics, systems integration, software, maintenance, and sustainment.
The company’s current presence in Lawton, Oklahoma, and Orlando, Florida also places it near important military and defense-related organizations. Its Lawton headquarters is close to Fort Sill, while its Orlando operation is located near the Central Florida Research Park and organizations involved in simulation, training, testing, and threat-related capabilities.
For organizations seeking government contractors with experience in technical support and defense readiness, AST represents a company with a long operating history and a broad range of capabilities.
